    <h2>Customizing SumatraPDF 3.2</h2>

    <p>You can change the look and behavior of
      <a href="http://www.sumatrapdfreader.org/">SumatraPDF</a>
      by editing the file <code>SumatraPDF-settings.txt</code>. The file is stored in
      <code>%APPDATA%\SumatraPDF</code> directory for the installed version or in the
      same directory as <code>SumatraPDF.exe</code> executable for the portable version.</p>

    <p>Use the menu item <code>Settings -> Advanced Settings...</code> to open the settings file
      with your default text editor.</p>

    <p>The file is in a simple text format. Below is an explanation of
      what the different settings mean and what their default values are.</p>

    <p>Highlighted settings can't be changed from the UI. Modifying other settings
      directly in this file is not recommended.</p>

    <p>If you add or remove lines with square brackets, <b>make sure to always add/remove
        square brackets in pairs</b>! Else you risk losing all the data following them.</p>
